Can't use sensors::temperatures function in different thread

[ravenclaw900]

If the sensors::temperatures function is spawned into a different thread, it fails with implementation of `std::ops::FnOnce` is not general enough.

MWE:

use futures::StreamExt;
use heim::sensors;

#[tokio::main]
async fn main() {
    tokio::spawn(async {
        sensors::temperatures()
            .collect::<Vec<Result<sensors::TemperatureSensor, heim::Error>>>()
            .await
    });
}
